Answer: equation of a linear function in point-slope form
Step-by-step explanation:
Given : The equation of a linear function in point-slope form passing through point [tex](x_1,y_1)[/tex] is
[tex]y -y_1 = m(x -x_1)[/tex]
The equation written by Harold correctly
[tex]y = 3(x - 7)[/tex]
It can be written as:[tex]y-0 = 3(x - 7)[/tex]
When we compare to the equation of a linear function in point-slope form, we get [tex]y_1=0,\ x_1=7[/tex]
Hence, the point used by Harold = [tex](x_1,y_1)=(7,0)[/tex]
